[Buildroot] wpa_supplicant not starting correctly

[Alexey Mednyy]

Hello there,

I've got configuration with eudev,dbus and  busybox init.
Previously everything worked fine, but now wpa_supplicant not starting.
and I see this in /var/log/messages :

Mar 25 22:56:25 hostname daemon.notice dbus[120]: [system] Activating
service name='fi.w1.wpa_supplicant1' (using servicehelper)
Mar 25 22:56:26 hostname daemon.info init: starting pideudev 146, tty
'/dev/ttyS0': '/sbin/getty -L  ttyS0 0 vt100 '
Mar 25 22:56:26 hostname daemon.notice dbus[120]: [system] Activated
service 'fi.w1.wpa_supplicant1' failed: Failed to execute program
fi.w1.wpa_supplicant1: Success

I'm not an expert in dbus, so asking for help what causes such problem?
I think before some recent commit wpa_supplicant started by init script
not by dbus is it true?

If you use network-manager or something managing wpa_supplicant, then
they have always relied on D-Bus activation to start wpa_supplicant.

You seem to not run systemd, so the standard D-Bus activation should
work.  Check that you can run wpa_supplicant normally (i.e. by running
it with the same parameters as specified in
/usr/share/dbus-1/system-services/fi.w1.wpa_supplicant1.service ).  If
it does, there is another problem.

My current supposition is that your wpa_supplicant was built without
D-Bus support.
